Abstract: Provided are methods of managing and storing distributed files based on an information-centric network (ICN). A method of managing distributed files performed by an ICN node includes receiving a message for requesting provision of data from a first network node, determining whether a name of the requested data is identical to a name of data stored in the ICN node, and adaptively providing the data to the first network node based on a result of the determination. Accordingly, it is possible to reduce the overall network load by preventing duplication of a data access path.

Abstract: A plurality of local management systems each manage at least one of distributed cloud centers, and generate individual resource information about the cloud centers they manage. A global management system collects individual resource information about the corresponding cloud centers from the plurality of local management systems, and requests cloud center resources while transmitting profile information in a resource container format to the local management systems according to users who have requested a cloud service.

Abstract: In a content network over which a plurality of smart nodes is coupled, each smart node receives advertisement messages broadcasted by adjacent smart nodes. The advertisement message may be one of a link state advertisement (LSA) message including link state information indicative of a link that is a network interface, a server state advertisement (SSA) message including server state information indicative of a data storage state and a processing state of a processing unit of the smart node, and a content state advertisement (CSA) message including content state information indicative of content stored in the smart node. Each smart node updates its own database based on the information included in the received advertisement message.

Abstract: In a content network over which a plurality of smart nodes is coupled, a content network management system receives information response messages including pieces of management interface base (MIB) information from smart nodes. Next, the content network management system classifies the pieces of MIB information included in the received response messages into server resource information, topology information, and network resource information, and stores and manages the pieces of information.

Abstract: In order to easily prevent traffic of a content data server, which provides an arbitrary content, from being overloaded, the content transmission system according to an exemplary embodiment includes a content data server which provides an arbitrary content to a plurality of terminals when a request signal for the arbitrary content is input from the plurality of terminals, a data control server which when the arbitrary content is provided, monitors whether the traffic of the content data server is overloaded and if the traffic is overloaded as a result of monitoring, generates a traffic distribution request signal, and a node control server which when the traffic distribution request signal is input from the data control server, controls to provide the arbitrary content to an arbitrary distribution node, which satisfies a setting standard among a plurality of distribution nodes, to be provided to an arbitrary terminal among the plurality of terminals.

The multilayer parallel processing apparatus includes two or more hierarchical parallel processing units, each configured to process flow data corresponding to a hierarchy that is allocated thereto in response to inputting pieces of flow data configured with two or more hierarchies, and a common database configured to be accessed by the two or more hierarchical parallel processing units and store processing results of each of the hierarchical parallel processing units.

Abstract: A parallel processing system determines whether to drive all or some processors so as to process data that are input based on capacity or time for processing the input data. Also, the system temporarily stores the data that are processed and output by the respective processors, and controls the same to be output when it becomes the calculated output time based on the traffic processing time for the input data.
